Ufo-Pu55y Posted March 8, 2008 Author Share Posted March 8, 2008 (edited) A selfkeygen (0 points.. cough) with one JNZ to JMP and some NOPs... ok. But why this weird overlay :? Trying to hide what ? ^^ If your overlay saves it to C:\ packed with FSG, then you shouldn't at least forget to delete it afterwards. Or maybe better save it to TEMP folder..

TGunner54 Posted March 8, 2008 Share Posted March 8, 2008 Oh... lol i was seeing if you would notice if it was a keygen or Self-Keygen xD i packed it with FSG and used D1S1G to make it look like UPX idk what D1S1G does.... i guess it extracts to C:\ then o.o?

DrPepUr Posted March 8, 2008 Share Posted March 8, 2008 (edited) I hope this is worth atleast 1 point...... My head hurts now.... Ufo_Pu55y_hASSh_2_Keygen.rar Edited March 8, 2008 by dustyh1981 Link to comment Share on other sites More sharing options...
Ufo-Pu55y Posted March 8, 2008 Author Share Posted March 8, 2008 (edited) I hope this is worth atleast 1 point...... Ofc But your code really made me wonder. For example you got some lstrcat in there and other weird stuff.. nearly looked like obfuscation to me :? The trick is to get a hasher which does them all. I got 2 hash functions in there. The 2nd is CRC16 - PEiD might have told you. So I got 2 main hash calls.. each with some parameters: ptrInput, ptrOutput and 1 or more init values. Maybe it was mean not to use usual inits. So you would first need to look up, what the inits might 'usually' be and try a call with such init. After that compare the output string with the outputs of a hasher to recognize the type of hash... I don't want to name the 1st hash, yet.. but for both calls I only changed 1 BIT in the inits Edited March 8, 2008 by Ufo-Pu55y Link to comment Share on other sites More sharing options...
DrPepUr Posted March 8, 2008 Share Posted March 8, 2008 I have no idea what the first hash is, I couldnt ever figure it out. I ripped the one out of the keygenme and used the lstrcat to set up the buffer.......Im sure it would have been easier if I could have figured out the first hash..........so I made the best of it.........oh well I tried....

Loki Posted March 11, 2008 Share Posted March 11, 2008 You're going to have to put me out of my misery on this one mate Easily rippable of course, but I'm really not sure what that other hash is. :s Link to comment Share on other sites More sharing options...
syk071c Posted March 11, 2008 Share Posted March 11, 2008 Oh goody something to keep me occupied on the weekend.. no solutions yet please Link to comment Share on other sites More sharing options...
Loki Posted March 12, 2008 Share Posted March 12, 2008 UFO told me what the hash is.... for all those as confused as I was, it isnt some 'completely' obscure hash. It is however, not one of the more commmonly implemented one. Good luck syk071c Link to comment Share on other sites More sharing options...

ChupaChu Posted March 12, 2008 Share Posted March 12, 2008 Besides hashing the algo is simple and easy to own.Whats hashing conserned; it needs time to trace it and understand it; i just dont have time for it at the time being.nice crackme, UFO!BR, ChupaChu!
